Fundamental System Design Principles for Simultaneous Mass Transfer and Chemical Reactions in Chemical Engineering Science: Including a Computational Approach with R is a comprehensive resource providing a fundamental description of the scientific basis for diffusional processes and mass transfer operations in the presence of simultaneous chemical reactions. In the book several models are presented, assessed, and showcased for engineering design applications. Based on a vigorous assessment of several theoretical models for mass transfer, a selected preferred methodology is recommended as a firm basis for engineering design. A design methodology is presented for the engineering of requisite equipment for achieving a given goal. Concomitant equipment requirements are derived to provide a solution matching specified pre-determined design objectives, such as the degree of purity of products as well as the amount of output per unit time. Presents basic scientific models of diffusional processes and mass transfer with simultaneous chemical reactions Introduces the use of the open-sourced computer programming language R, for quantitative assessment in the analysis of models for simultaneous mass transfer and chemical reactions analysis Provides in-depth quantitative methodologies for engineering design calculations of NTU and/or NTP for designing the contacting conditions required to provide the needed degree of mass transfer for achieving stated design goals Recommends and specifies the required amount of hardware (heights of packings or the number of contacting plates) to achieve the needed mass transfer operation
